I _{would like to begin my discussion today by conveying my sincere greetings and love to all the members of the esteemed congregation.।}

There is no end to knowing and learning. If it is a technical matter, then the issues will be a little more complicated. But in completing this task, I have learned a lot more and I want to give full credit to Saiful Bhai. So let's start my presentation.

Explain the security features of blockchain?

Since blockchain is a decentralized technology, there is absolutely no possibility of data tampering or theft. Because it is an open platform and the information is always updated. Also, all the information is open to everyone and every transaction is encrypted by cryptography. And the connection is made between each block using hashing technology. And if one wants to change the information of a block, the information that everyone else has will remain the same and everyone else will understand that someone has changed or tried to change the information of that block. So it can be said that blockchain technology is the best in terms of security.

What do you mean by blockchain mining?

In a blockchain system, every transaction from an account in each block is driven by a management chain. Again, each block is secured by hashing, which is a very high-security system. And if anyone wants to be able to access this data from any part of the world because it is a decentralized technology. They are given some tokens for the job and this is called mining. And their job is to verify all the transactions and create a hash code for each transaction. It will be normal to have the information of the transaction. And in this way, one block is created and the previous block is read and merged with the block to form a chain and this is called the blockchain. And when the blocks are with the chain. It is impossible to change or delete them when they are connected, but miners can change more than half of them together if they want to. But that is impossible. It is never possible to combine.

What do you mean by the DPOS system of mining? Distinguish between proof of partnership and proof of work.

The DPOS system is like a democratic system. Normally those who are minors are also selected. In other words, all the users here are selected based on their preference or the basis of votes. More. And the amount of votes depends on the user's share. The more shares, the higher the voting value.

Most of the cryptocurrencies that rely on blockchain lasers usually rely on proof-of-work algorithms. Pow peer-to-peer network systems that provide real-time decentralized payment settlement. And reduces overall transaction costs by reducing all types of redundancy. Usually, miners find a solution to that block first to add a new block to the blockchain. And when he can do this, he is rewarded with newly created coins.

Those who buy a lot of native tokens in a particular blockchain are mainly involved in mining. This is called the Proof of Steak System of Mining.

Why is unlimited trade important?

At present, we have not been able to ensure economic transparency or accountability. Some powerful people in the world think that war is collapsing the economy again due to nefarious motives. And all these things have to be compensated for the low-income countries. So in this age of technology, we should change the economic system where there will be no borders and everything will be clear. And blockchain is the only best option.

Distinguish between cryptocurrency and blockchain:

Blockchain is just a technology to record data. And cryptocurrency is a kind of digital currency. Cryptography is used to maintain its security. Blockchain is the name of a technology where crypto is running on this technology.
